Detailed ways

The core of the present invention is that the sender sends the short message carrying the short message deletion report feedback request information; correspondingly, the receiver feeds back the short message deletion request information to the user terminal that sent the short message according to the short message deletion report feedback request information. The report information realizes that when the user receiving the short message deletes the short message that has requested the short message deletion report, the receiver automatically feeds back the short message deletion report information to the sender.

The present invention is described in detail below in conjunction with accompanying drawing, with reference to Fig. 1, this figure is the main flowchart of short message transmission method of the present invention, specifically comprises the following steps:

Step s1, the sender sends the short message carrying the short message deletion report feedback request information;

In step s2, the receiver feeds back short message deletion report information to the user terminal that sent the short message according to the short message deletion report feedback request information.

With reference to Fig. 2, this figure is the schematic flow chart that the sender of short message transmission method of the present invention sends short message, specifically comprises the following steps:

Step s11, the sender judges whether the short message to be sent has activated the short message deletion report feedback, if so, executes step s12, otherwise, executes step s14;

Step s12, adding short message deletion report feedback request information for the short message to be sent;

Step s13, sending the to-be-sent short message to which the short message deletion report feedback request information has been added, and storing the short message at the same time;

Step s14, directly sending the short message to be sent.

It should be noted that the present invention is based on the Short Message Service (Short Message Service, SMS) related protocol of the Third Generation Partnership Project 2 (The Third Generation Partnership Project2, 3GPP2), and the short message deletion report feedback request is all in the reply option (Reply Option) This bearer data sub-parameter is set. Now, there are four more reserved bits in this subparameter. We can now take out a short message deletion report request (DEL REQ) from the reserved bit to indicate whether to request a short message deletion report (Delete Report). When DEL_REQ="1", it means to request to delete the report, and when DEL_REQ="0", it means not to delete the report.

In addition, the present invention fully considers that the storage of the short message requesting to delete the report by the sender is the least change to the prior art. In practical applications, it can also be stored in the short message center of the server, but it will increase the storage capacity of the short message center. burden. At present, the function of the user terminal such as the mobile phone to store the sent short message has two forms, one is to automatically store the sent short message, and the other is to prompt the user whether to save the sent short message. When the present invention is implemented, if If the user terminal sending the message is set to request for short message deletion report feedback, it will not affect the mobile phone that automatically stores the sent message, but for the mobile phone that can choose whether to save the sent message, it will be automatically set to "save the sent message", And at this time, the user is no longer allowed to modify, until the user chooses not to request to delete the report, the function of setting whether to save the sent message can resume normal use.

With reference to Fig. 3, this figure is the schematic flow chart that the receiving party of short message transmission method of the present invention receives short message, specifically comprises the following steps:

Step s21, the receiver judges whether the short message from the sender carries short message deletion report feedback request information, and if so, executes step s22 after deleting the short message, otherwise, executes step s22 when deleting the short message s23;

Step s22, feeding back the short message deletion report information to the sender who sent the short message;

Step s23, directly delete the short message.

In the above-mentioned step s21, after the receiving party judges that the short message from the sending end is a short message carrying the short message deletion report feedback request information, when deleting the short message, the short message deletion is fed back to the sender who sent the short message. As for the report information, in implementation, a specific feedback time can be set in the deletion report feedback request information, for example, 20 seconds after the short message is deleted.

With reference to Fig. 4, this figure is the flow diagram that sender receives and processes short message deletion report in the short message transmission method of the present invention, specifically comprises the following steps:

Step s31, the user terminal sending the information receives the information;

Step s32, judging whether the information is short message deletion report information according to the information type field carried in the information, if so, execute step s33, otherwise, execute step s36;

Step s33, judging whether the short message corresponding to the fed back short message deletion report is stored with the deleted information identification field, if so, execute step 34, otherwise, execute step 35;

In step s34, the sender prompts the user that the stored short message has been deleted by the user who received the short message. Two methods can be used in the specific implementation, one of which is corresponding to the deletion report stored in the sender. Add the icon that the short message has been deleted before the short message, and another way is to add the sent short message corresponding to the short message deletion report information to the short message deletion report information by prompting the user to view the short message deletion report The information prompts the user that the short message has been deleted by the receiving end user;

Step s35, determine that the short message corresponding to the short message deletion report has been deleted by the user who sent the short message, at this time the sender can directly discard the short message deletion report information without notifying the user or use a similar "this is a deletion report" , corresponding to the message "You have deleted it and cannot be displayed", the notification tone informs the user who sent the short message;

Step s36, process according to the prior art.

The above-mentioned short message deletion report information is described below, the present invention uses the existing sub-parameters in the existing protocol to set the short message deletion report, mainly including the following parameters:

Message Identifier: message identifier;

User Data: user data;

Message Center Time Stamp: message center timestamp;

Multiple Encoding User Data: Multi-encoding user data;

Message Deposit Index: message deposit index;

Among them, User Data, Message Center Time Stamp, Multiple Encoding User Data, and Message Deposit Index are all optional parameters; Message Identifier is a required parameter.

The deletion report information can only carry a bearer data sub-parameter information identifier (MessageIdentifier), or you can configure various bearer data sub-parameters for the deletion report to achieve more functions. For example, you can use the time stamp sub-parameter (Message Center Time Stamp) to describe The time of deletion, using the Message Deposit Index sub-parameter to illustrate the content of the deleted short message, etc., and is not limited to the above content.

Refer to Figure 5, which is a schematic diagram of the definition of the Message Identifier parameter.

Among them, SUBPARAMETER_ID＝00000000 means that this is the Message Identifier subparameter;

SUBPARAM_LEN=00000011 means that there are 3 octets after this;

MESSAGE_TYPE=1001 means that the message type is short message deletion report message.

Other fields still follow the definition in the protocol.

The present invention adopts the message identification field (Message_ID) of above-mentioned Message Identifier to be used for uniquely determining the field of a short message, and this field value is equal to the value of the MESSAGE_ID field of the short message that is deleted, and sender sends a short message every time, and MESSAGE_ID all can add one , For example, for a mobile phone, when sending the first message, MESSAGE_ID selects a random number modulo 65536 from 0-65535, so for this mobile phone, the sent short message can be distinguished by MESSEGE_ID, so that the received information can be identified Which short message has been deleted by the user; at the same time, the message type field (MESSAGE_TYPE) of Message Identifier is used to identify the message type, and by the value of MESSAGE_TYPE, the user terminal receiving the message deletion report can know that this is a short message deletion report information.
